WL1831MOD: Change Bluetooth MAC address

Part Number: WL1831MOD


Hello,

We are looking to write and change BT MAC address in the module.
We use the HCI command : Send VS_Write_BD_ADDR (0xFC06) command.

1
hcitool cmd 0x3f 0x0006 0x01 0x23 0x45 0x67 0x89 0xab

It works correctly, but if we restart the module and the firmware you have to redo the command.
Is it possible to write a "definitive" BT MAC address in the non-volatile memory ?

What is the procedure to burn the default address into the chip ROM ?
Thank you.
Regards,
Dayan LOMBARDI
